A further object is to providea convex groove in glass sheets wlthside" walls s0 sha ed as to throw a shadowjon the convex surace. x x With these and otherob'ects and advantageous features in view, t e invention `conpanyin Vim sists of novel arrangements of parts/more fully disclosed in the detailed description following, in conjunction with'the `accomdrawings, and more particularlyv set fort in the appended claims@ In the drawings: i Fig. 1 is a plan view showing a` glass "sheet with the novel decorative' grooves diagonal- 1y disposed thereof;

Fig. 2 is a similar plan view showing the novel grooves used as a border; f o Fi 3 is an enlargedcross-section of the walls; and p Fig. 4 is an elevation of the novel groovecutting tool.

It has been found desirable in glass ornamentation to decorate the surface of glass; sheets with grooves which may either be polj ished, or may be left `unpolished to Aresent a pleasing gray appearance. y a novel groovew Ich resents an attractive appearance, ing weakening of the glass sheet, andwhich includes'a central domedor convex portion and inclined side walls, the side walls casting *1' pleasingl shadows on the/central 'convex tion, w
